You'll have to wait until next week to see the full trailer for Christopher Nolan's Oppenheimer, the film that tells the story of the phycisist Robert Oppenheimer and his part in the creation of the atomic bomb. And also after that, during the Cold War, as CinemaCon attendees saw Wednesday night. Nolan himself appeared on stage during Universal's presentation to present a sizzle reel of clips from the film to whet the appetites of assembled movie theater owners.

"I know of no more dramatic tale with higher stakes," Nolan told the crowd, before letting the footage from the film roll.

It began in black and white, with Senator Lewis Strauss (Robert Downey Jr.) learning that the Soviets have an atomic bomb of their own. Strauss isn't happy that the US is apparently falling behind in the nuclear arms race.
